Bi‐Modified Bi2WO6/BiOI Heterojunction with Enhanced Visible‐Light‐Driven Photoactivity for Antibiotic Degradation

“…Very recently, several Bi 2 WO 6 -based photocatalysts, such as Au-Bi 2 WO 6 [17], Ba-doped Bi 2 WO 6 [18], Bi 2 WO 6 /BiOI [19], and Bi 2 Mo x W 1-x O 6 [20] had been successfully prepared, which effectively improved the electron-hole pair separation efficiency and visible light absorption efficiency of the catalysts by metal doping or forming heterojunctions with other semiconductors. It was widely accepted that the charge separation efficiency can be improved by introducing metal Au [21,22], Ag [23,24] and Bi [25,26] nanoparticles due to surface plasmon resonance (SPR) effect. In addition, it was found that the formation of heterojunction with other semiconductor was beneficial to improve the light absorption characteristics of Bi 2 WO 6 .…”

Hematite nanoparticles decorated nitrogen-doped reduced graphene oxide/graphitic carbon nitride multifunctional heterostructure photocatalyst towards environmental applications

“…87-1526). 51 The former peak located at 13.0° corresponds to the in-planar packing motif of tri- s -triazine units, while the latter situated at 27.4° corresponds to the interlayer stacking of conjugated aromatic segments, respectively. 52 In the observed XRD pattern, the appearance of several diffraction peaks at 2 θ : 33.2°, 35.8°, 49.6°, 54.2°, 57.1°, 62.6°, and 64.1° were marked by the miller indices (104), (110), (024), (116), (018), (214), and (300) planes, respectively which denote the successful formation of the hematite phase of iron oxide (α-Fe 2 O 3 ) according to the JCPDS No.…”

One-step thermal polymerization synthesis of nitrogen-rich g-C3N4 nanosheets enhances photocatalytic redox activity

“…10–12 To address the above mentioned problems, various modification methods, such as doping foreign elements, morphology design, constructing a heterojunction with g-C 3 N 4 -based, and engineering defects with vacancies, have emerged to enhance the photocatalytic activity. 13–18…”
